Just to add on some clues, this issue seems to be linked to something called "TinyConfig". Here's the log on my side using of the RPG series mods:

java.lang.RuntimeException: java.lang.IllegalAccessError: class net.tinyconfig.FabricHelper (in module paladins._1._21._1.TinyConfig.mapped.moj._1._21._1) cannot access class net.fabricmc.loader.api.FabricLoader (in module org.sinytra.connector) because module paladins._1._21._1.TinyConfig.mapped.moj._1._21._1 does not read module org.sinytra.connector
